Application filed July 25, 1911. Serial No. 640,478.

To all whom 'Lt may concern: screws 7C, suitable insulating spacing sleeves Be it known that l, HAROLD E. BECK, a 7d being mounted on said screws inside the citizen of the United States, residing at aashell and between the motor and shell.

An insulating-supporting disk 10 is rigidly mounted on the bushing l1 surrounding the shaft 5 and held in place by 'means of a "set screw l2. At Vthe outer periphery of this zdisk is mounted a circular --series of fan .blades i3, said blades being soldered, brazed or otherwise connected .at their ends to ine- :tallio rings 13, the ring adjacent the dish. 10 being secured to said disk by screws lill. VOn the inner periphery of this series of blades is mounted a circular frame 14; coinvprising the spider arm 14a rigidly secured to :the blades in any suitable manner and a perforated circular plate or shoe lib constituting one elect-rode of the machine. This ,plate or shoe 14 may be supported independently of the blades of the fan, or otherwise, if desired. lt will be noted that. these .members heretofore described consisting of the fan, frame and the perfi'irated plate are secured to the insulating disk Vl0 and adaptof Illinois have invented new and useful Improvements in Ozonizers, of which the following is a full, clear, oncise, and exact description, reference being had t-o the acspeci tication.

My invention relates to improvements in ozonizers, iny objects being to simplify the' construct-ion of such devices, to render them more compact' than heretofore7 to increase the efficiency thereof so far as the purification and ozonization effects on the air are concerned, and to provide a machine which initself is capable of dischargino` a strong and powerful current of thoroughly purified and ozonizedair which, if desired, may be delivered through a suitable system of pipes or tubes to the room or rooms, or places where it is intended to use the same.

Further .objects will appear from the 'de tailed description and claims to follow, referenoe being had to the accompanying drawings illustrating one embodiment Of-my inn vention, in Which- Figure 1 represents a side elevation of my machine partly in section; Fig. 2 represents an end elevation of my machine partly in section:l and Fig.' 3 represents 'asimplified diagram of the electrical circuits. A

'Like numerals of reference indifcate like .parts in` the several figures of the drawings.

Referring now to the drawings, i represents a motor preferably of the 'alternating the motor and concentric therewith is a .transformer box 25 of insulating material, preferably secured to the shell or casing T by screws 23 passing through the -insulated spacing sleeves 24, or 'such supportingscrews may be dispensed with and the motor alone be utilized for the support. y

A. glass cylinder' il) forming the dielectric of the machine is mounted on the ruiter surface of this transforiner box '23, the inner edge of said cylinder at the right in lfuig. 2 engaging with a concentric shoulder fzob'on the transformer box, and the efuresponding edge at the left engaging with an insulating .band or ring 25a fitting between said glass cylinder and the box. lhis ring or band Q5 is slipped iiito posit ion aftei` the glass bearings for the shaft, and since the motor is cylinder has been placed ui position with its itself supported from the. casing these additional bearings V6 may be dispensed with if desired ,but I prefer` the arrangement shown. This shell or casing, which is made of any opposite edge engaging the shoulder of the transformer box.

On the inner surface of the glass cylinder and within the open space between it and the face of the transfzn'lncr box is mounted a thin. metallic iilni '20, preferably in the form of tin foil, and constituting the lother electrode of thevderice. This tin toil is ap- `,lied to the inner face of the cylinder before the latter placed in position on the transformer box. By providing the removable ofspiral form and preferably formed of two pieces 7*11 .and 7l screwed together, as shown at S, and having a discharge opening 9. The tor is fixed to the shaft 5, while the shell or is secured to the shell or casing 7 -by the ed to revolve with the shaft 5. Surrounding strip o r ring 25, which is placed in position after the glass cylinder is in place, tlie tin fpil is not scratched o r scraped off in asseminv.

Oli-ie end of the transformer box, usually that-atv the left in Fig. 2, is removable (not shown) and within the box is placed a suitable transformer, consisting of a primary winding 22 'of comparatively coarse wire and few turns, and a secondary winding 22a of comparatively fine wire and a large number4 of turns. p One terminal of the secondary winding is "connected in any suitable manner, as by a 'conductor 29, with the tin foil electrode; and

the other terminal is connected in a suitable manner, diagrammatically indicated by a conductor 30, with the brush 31 of ordinary construction, mounted in a bushing in the shell and bearing at its inner end on the ring 32 carried on the outer face of the insu? lating disk 10. The ring 32 is suitably connected by a conductor 33 with the other electrode 14. i'

One terminal of the primary winding of the transformer is connected, as diagrammatically indicated, by a conductor 341' with one side of the power circuit 35, while its other terminal isconnected as by a Wire 36 or other conductor with one brush of a rotary make and break device 26, the segments of which are or may be mountedon an eX- tension of the armature shaft 5, the opposite brush of said device being connected by a suitable conductor 37 with the opposite side ofthe power circuit 35. A suitable condenser 28 is connected around the make or Abreak device 26 to prevent sparking. The power circuit 35 leads directl to the motor, and is of the ususal type o alternating current circuit for lighting purposes.

n In the operation lof my device the motor 1s started by the switch (not shown) and the c urrent flows also through the primary Winding of the transformer and' the make and break device, the sparking being taken of the air gap, which is continuallybeing brought into contact with the" fresh air drawn in from the side of the casing through the openings 31a and forced by the' action of vthe fan blades ra idly around the interior of the casingan out by way of the ldisf charge opening 9. As clearly shown in Fig.

1, the available air space commences at a point 32 and is practically nil but enlarges until it attains the area of the. discharge opening 9.' It is thus evident that by oper-v ating the motor, the fan draws in and discharges under pressure a large amount of air; the air thus discharged practically all passing through, around and between the electrodes which produces a comparatively great amount of ozone, thereby purifying and charging the air with ozone. Owing to the construction of the fan any desired pressure may be imparted to the air current discharged, and it may be :conducted from the machine by any suitable system of piping without the necessity of employing other fan or pressure creating device.

It is evident, ofl course, that the rapid revolution of the fan blades which force i the air out in the direction indicated tends to form a vacuum between the inner edges of the blades and the outer surface of the perforated plate, that is, in the spaces 34 between the frame supports, thus vinsuring that a sutiicient lquantity of air will be subjected to the ozoniz'ing influence of the electric sparks. l

The brush `18, passing through a suitable slot inthe plate 14", has its supporting lever pivot-ed at 16 to the arms 111, which leveris weighted at its opposite end 17. The outer surface of the dielectric or L lass cylinder 19 is thus kept free from t e dust or dirt which would naturally settle thereon, and which, owing to the action of the electric arc, is vliable to carbonize and cake on the outside `of the glass. The centrifugal force exerted on the ball or weighted end 17 of the lever lightly forces the brush in- Wardly and causes it to bear against the face of the cylinder with just sufficient force to remove the dust,.dirt and carbon and at the sameltime without undue wear upon the bristles.

My device' is one that is of very simple construction, can be readily assembled and disassembled and possesses no complicated parts that are liable to get out of order. Any ordinary motor can be used and the blades of the fan, While`shown at certain angles .and in certain positions, may, of

course, be varied to meet the exigencies of the case. So, also, the peculiar shape of the casing itself. I do not limit myself to such configuration, as other shapes may be used, by means of which the beneficial results attained by my device inayalso be attained.

' While I Ahave shown the Vconductors in a more or less diagrammatic form for the lsake of'clearness, it will, be understood by those skilled in the art that in practice they may be of any desired construction and arrangement to accomplish the purposes intended. For example, the connection of the CES, SY

The condenser 26 is of the desired typ'e and capacity and supported on Athe casingor otherwise' as V desired. p i

Various changes and modifications within made. If theapparatus be employed in a is sufficient to rotate the fan, the motor, of course, need not be employed.
